I just got the AAM fuel return system and put it all together yesterday. I'm trying to start my motor with 8.5:1 comp ratio for the very 1st time and it runs for a few seconds and shuts down.

I believe I need to gap the plugs differently now that my compression is lower and I don't know how to work the aeromotive fuel pressure regulator. If I do need to gap differently, what is the propper gapping?

do I hook up the top mal fitting to the vacuum lines?

HELP PLEASE!!!!
